This probably means something is wrong in signaling, because the _b2b-1 leg is not supposed to reach proxy. it's going like:

Caller UA -> lb -> proxy -> sbc as 3c27555c7c6b-4ikbkvf770jq sbc -> lb -> Callee UA as 3c27555c7c6b-4ikbkvf770jq_b2b-1

Maybe the Routes are wrong somewhere and BYE with
3c27555c7c6b-4ikbkvf770jq_b2b-1 is going from lb to the proxy skipping sbc, need a trace (preferably as .pcap file) to tell that for sure..
